[Quadruple treatment with doxycycline, furazolidone, bismuth and proton pump inhibitor is still effective against Helicobacter pylori in our population].

Our objective is to determine the effectiveness of a therapeutic regimen for helicobacter pylori that includes a proton pump inhibitor, doxycycline, furazolidone and bismuth in our location. We carried out a retrospective study, non-randomized, in a private hospital in Lima, Peru. Patients with biopsy and/or rapid urease test proven helicobacter pylori infection after an endoscopy, from January 2017 to October 2022 were included.

[Difficult or Complex Bile duct stones in ERCP: Large Balloon Dilation and other stone management methods. Accumulated experience in a referral Endoscopic Center 2009- 2018.].

Introduction: Bile duct stones constitutes 20% of symptomatic gallbladder disease and difficult stones are one third of this. Endoscopic papillary large balloon dilation (EPLBD) with or without prior endoscopic sphincterotomy (EST) produces excellent outcomes for the treatment of complex or difficult common bile duct (CBD) stones, alone or combined with previous therapeutic options as mechanical lithotripsy (ML) and temporary or definitive stenting.

Objectives: Show success rate, complications and adverse events.

[New simplified regimen for Helicobacter pylori eradication achieves high effectiveness. Prospective study in a private clinic in Lima, Peru].

Objective: To determine the effectiveness of two new therapeutic regimes for Helicobacter pylori versus triple therapy that includes a proton pump inhibitor, amoxicillin and clarithromycin.

Materials And Methods: prospective study, non-randomized, in a private Hospital in Lima, Peru. Patients with biopsy and/or rapid ureasa test proven Helicobacter pylori infection received one of the three therapeutic regimens and were followed with a urea breath test 1 to 6 months upon completion of therapy.

[Utility of the capilar pattern in the NBI diagnosis of superficial lesions of the colon: prospective validation in a private endoscopic center Lima, Peru].

Introduction: It is important to detect and remove adenomas in order to prevent colon cancer. Angiogenesis is an early change in the pre malignant transformation sequence and narrow band imaging (NBI) allows for better visualization of the capillary pattern of the mucosa.

Objective: We present our data regarding the assessment of superficial lesions of the colon on colonoscopies using NBI as well as the Sano-Emura classification.

[Expected and unexpected adverse events in the therapeutic endoscopy of the bile duct (ERCP): experience of a private national center in 1356 consecutive cases (1999-2008)].

We report our experience of 10 years in therapeutic procedures of the bile duct (ERCP), describing adverse events or major and minor complications. We describe the associated factors, management, and risk age groups. We comment on the measures taken to prevent and treat them.
